Hi Guys,

In this blog,I will explain you how to merge two array in In PHP, array_merge() is a builtin function that is utilized to merge one or more arrays into a single array. We utilize this function to merge multiple elements or values en masse into a single array which occurs in such a way that the values of one array are appended to the precedent array. In an array, if we have the same string key reiterated, then the precedent value for the key will be overwritten by the next one.

Syntax:
array_merge(array1, array2, array3, ...);
Example:1 Note: If two or more array elements have the same key, the last one overrides the others.
<?php
    // Indexed array example
  $arr1 = array("Parth","Ramesh","Suresh");
  $arr2 = array("Jaymeen","Pratik","Sanjay");

  $arrMerge = array_merge($arr1,$arr2);

  print_r($arrMerge);
?>
Output
Array
(
    [0] => Parth
    [1] => Ramesh
    [2] => Suresh
    [3] => Jaymeen
    [4] => Pratik
    [5] => Sanjay
)

Here, I will give you full example for Merge two associative arrays into one array.

Example:2
<?php
  // Associative Array example
  $array1 = array('key1' => 'test1', 'key2' => 'test2');
  $array2 = array('key3' => 'test3', 'key4' => 'test4');

  $result_Array = array_merge($array1, $array2);

  print_r($result_Array);
?>
Output
Array
(
    [key1] => test1
    [key2] => test2
    [key3] => test3
    [key4] => test4
)

It will help you..
